If I want to buy/sell parts on FB Marketplace, how important is feedback, profile, and friends?

I've been selling on FB for a while now. I have two accounts. One for business and one for family. My kids post family stuff and I keep that separate from my business.
I'm an actual business and show my business card in my pictures. I will say that FB has got real bad with all the scammers. Worse than C/L. Scammers will steal your ad thus my business card that prevents that.
There is an entire group that is ran by scammers. MOPARS CARS & PARTS ONLY SWAP MEET. They always have a ton of really nice stuff real cheap and all of it is a scam. They have stolen my ads that I didn't show my b/card in. Don't ever send any money to anyone in that group. If you call them out they will delete your post and expel you from their privet group. FB has been notified about them and they don't care.
Join a bunch of Mopar groups. There are a lot of good legit groups. Also find local classified groups for your area. I post my ads in 20 different groups at a time.
Anymore I sell way more on FB than I do on the Mopar sites such as here. You will always have some *** clown respond to your ad or post. I just delete their post and then block them then they don't exist anymore.
